A randomized 25 question test from a pool of 761 questions, good luck!
There are numerous I/O modules that a typical DCS has access to. Which of the modules below is described as one that coverts the analog signals from T/Cs and RTDs to a digital signal?
IPv4 and IPv6 are the two current versions of IP. Which of the answers below is the defining difference between the two protocols?
DCS commonly is considered a computerised control system for a plant that has central operator supervisory control. Which of the terms below is best described as controllers and operator stations that are separated physically from the central control system?
The limits of a OUT parameter status field has several different classifications. Which of the classifications below can be described as the indication of a parameter within the set range?
In the protocol specifications of Modbus, there are only four types of registers that can be accessed by the master. Which of the terms below is best described as a discreet output memory location?
All the wired network components interact with ISO layers. Which of the answers below reflects the ISO layers that the NIC interacts with?
A typical DCS has at least four layers in it's architecture. Valves, switches and transmitters are all under the direct control of which of the layers below?
Providing power to remote sites in a SCADA system has several difficulties associated with it. Which of the answers below would be best defined as one that is used for continuous power generation where there are no other options?
All the wired network components interact with ISO layers. Which of the answers below reflects the ISO layers that the router interacts with?
Which of the topology connections is the most typical for a HART communication device?
There are commonly two configurations a programmer would use for workstations. Which of the answers below would best be described as a workstation that has the majority of the data processing done by the server?
Which of the recommended standards would be best described as having a half -duplex transmission system?
Modbus has standard command codes to allow the master to access information from it's slaves. Which of the commands below would be used to write the contents of a series of 10 coils to the slave device?
Alarm management is based upon the process conditions model. Which of the conditions in that model could be described as the optimal operating conditions?
Ethernet/IP is based on a protocol that the higher OSI layers of DeviceNet uses. Which of the answers below is the correct acronym for this protocol?
A defined area of geographical coverage is commonly called an area network. Which of the area networks below is the second smallest in area covered?
IPv4 network classes can also be defined by the IP address they use. Which of the answers corresponds best to the address in row "F"?
In the protocol specifications of Modbus, there are standard 5 and 6 digit addresses, each address starting with a specific number for the register type. Which number below starts the input status registers addresses?
With any GUI, there are opportunities to use gathered data visually. Which of the methods below would be best described as one that would allow an operator to retrieve and plot data over an extended time frame?
Historical data can be logged through a HMI application. Which of the data storage methods below would best be described as one that has superior acquisition of events, but does not use it's storage space effectively?
Which of the answers below best represents the first bit sent in a RS-232 asynchronous frame?
A media access control address is the name of the physical address that the Ethernet uses. Which of the answers represent the number of bytes that make up this MAC?
In a typical GUI, values take one of four generic indicators. Which of the indicators below would best used where discrete data needs to be provided, but a simple colour change will suffice?
Software for programming or configuration is an integral part of any HMI. Which of the interfaces below can be best described as where the bulk of the GUI applications are configured?
